- Abstract
Ginger (Zingiber officinale Rosc.), originated in the Indo-Malayan region, is now widely distributed across the tropics of Asia, Africa, America and Australia. It was domesticated in India and China, which represent the centre of origin of the species. Cultivated ginger though sterile, exhibits variations in rhizome and vegetative characters. The crop is gaining importance as a curative agent for a variety of ailments. Yield and quality traits (such as essential oil, fibre and oleoresin contents) along with volatile and non-volatile constituents are important determinants of the commodity's end product. Cultivar diversity for yield and morphological features is well known in ginger with few primitive types having excellent quality. However, the common name(s) of ginger cultivars are confusing and have resulted in geographical bias in its ex situ conservation. Most of the molecular/biochemical marker studies reported in ginger show low levels of polymorphism in contrast to plentiful phenotypic variability recorded in the species. The large influence of environmental factors on the content of key compounds, lack of seed set and confusion of the common names are the leading constraints to further varietal improvement of ginger. As tailor-made ginger varieties assume future significance these aspects will have relevance.
